AC ELECTRICAL CHARACTERISTICS
⎯ E ⎯ N ⎯ A ⎯ B ⎯ L ⎯ E = 0V, No R
Note 1: Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.
Note 2: Input pins (+IN, –IN) are protected by steering diodes to either
supply. If the inputs go beyond either supply rail, the input current should
be limited to less than 10mA.
Note 3: The LTC6401C and LTC6401I are guaranteed functional over the
operating temperature range of –40°C to 85°C
Note 4: The LTC6401C is guaranteed to meet specifi ed performance from
0°C to 70°C. It is designed, characterized and expected to meet specifi ed
performance from –40°C to 85°C but is not tested or QA sampled at these

temperatures. The LTC6401I is guaranteed to meet specifi ed performance
from –40°C to 85°C.
Note 5: Input and output baluns used. See Test Circuit A.
Note 6: Measured using Test Circuit B. R
Note 7: Since the LTC6401-26 is a feedback amplifi er with low output
impedance, a resistive load is not required when driving an AD converter.
Therefore, typical output power is very small. In order to compare the
LTC6401-26 with amplifi ers that require 50Ω output load, the output
voltage swing driving a given R
